While it isn't a done deal in terms of Abrams as director, the site does note, "Abrams has just returned from vacation and is hunkering down with writers Roberto Orci, Alex Kurtzman and Damon Lindelof to work on the Trek script and beginning prep for a Trek sequel that will likely begin production in January... Abrams hasn't formally committed and hasn't approved a script yet, but the studio has exercised its option on the cast and they will be ready when Abrams is."
The story goes on to state that the shift in Trek production schedule will mean a delay for Chris Pine's reboot of Tom Clancy's Jack Ryan adventures.
If Star Trek gets delayed until 2013, that would mean four years between films -- that's like half a century in Hollywood years!
